Question: Goldbach's conjecture states that every even natural number except 2 is the sum of two prime numbers. For Example, 24 = 7 + 17 and 16 = 3 +13. Write each even number from 30 to 40 as the sum of two prime numbers.
LOL! I don't understand a word it says! PLZZ help! hahaha.

In short: Every even number (2, 4, 6, 8...) except the #2 can be the sum (like if 2+2=4, 4 is the "sum") of two prime numbers (a prime number is a number that can only be divided by 1 and itself, such as: 3, 5, 7, 11)
I'll get you started off:
30=15+15
28=17+11
26=19+7

What don't you understand? You even have two examples!
There's no formula for it, you'll need to just try different primes
I'll do 36:
2+24, no
3+33, no
5+31: Bingo there's two primes that add to 36.
Now just do the same for the even numbers between 30 and 40.
Heck, there's only 6 and I did one of those!!!

break down each even number..30, 32, 34, 36, 48, 40
30=27+3, 17+13, etc
but, do yourself a favor and get either a classmate/friend or teacher to review this with you so YOU can get it!
a lot of math is "language" and we all need a translater at some time or other. good luck! :)

that makes perfect sense.
30=7+23
32=3+29
34=11+23
36=7+29
38=7+31
40=11+29
that was easy. what kind of school do you go to?
